Visual Fields Screening Test
Sunday, April 30th, 2006The Visual Fields Screening Test is administered separately to each eye starting with the left. Options are presented that allow you to skip either eye. The patient is directed to stare intently at a series of 1 digit numbers being continuously displayed at the center of the screen. Then the patient simply clicks the mouse button immediately, every time he/she detects that a small white spot is being displayed somewhere on the screen. A response by the patient is added to the data pool only if the patient is able to correctly identify the last number that was displayed at the center of the screen at the time he/she clicked the mouse button. The program produces a visual field map, for each eye tested, based upon the patient’s reaction times. To save the map the clinician must click on a Print button to have the map printed.
